As what everyone else has said, it's good that you're ok but you need to make sure your knee is ok and call the officer. The guy was being a jerk and HE was in the wrong, NOT you. That being said, don't be hard on yourself, you were being a good person and taking his word for it, not knowing he wasn't gonna keep his end of the deal. You're not stupid, he is. And, it's ok to be apprehensive about riding after the accident, that's normal. Just don't let it run your life. If you love to ride, start back easy, on MUTs and in the early am or late pm. Hope everything works out.
